Vitamin B12 is part of a larger vitamin B complex, but it is regularly singled out as an essential vitamin

that is necessary for good health. For this reason, more and more people are choosing to supplement their

diet with vitamin B12 shots. B12 is a naturally occurring vitamin found in animal products such as meat,

eggs, and dairy.

It is important for the proper functioning of the circulatory and nervous systems. Vitamin B12 plays a

critical role in red blood cell production and provides energy for the brain to function smoothly.Most

people get enough B12 from diet alone, especially if their diet includes lots of animal products. However,

even a slight deficiency can cause problems that may seem minor at first but can escalate if the deficiency

is not addressed.

Common signs of a slight deficiency include fatigue, difficulty in remembering, light-headedness, and

constipation or diarrhea. These problems can persist if a deficiency is left untreated.

The reasons for why people start using B12 injections are numerous. So what do B12 shots do?

 Since vitamin B12 is associated with neural and cognitive functioning, some people take B12 to

improve mood, energy, and concentration.

 B12 in addition to several amino acids helps the body metabolize fat, which is a great tool that

helps people lose weight.

 Vitamin B12 plays a key role in the circulatory system, and high levels of B12 can reduce

homocysteine levels. Homocysteine blocks the arteries and taxes the heart, so by reducing

homocysteine levels, vitamin B12 reduces the risk for heart disease and stroke.

 By helping the body regulate your circadian rhythms, vitamin B12 can help you sleep better.

 Vitamin B12 provides a boost to the immune system by making the rest of the body run more

smoothly, which can reduce chance of illness.

 There are certain people who should pay particular attention to the benefits of B12 shots, though anyone

could reap the benefits of B12 injections. Some people who may want to pay particular attention and know

what do B12 shots do include

 People who do not eat animal products, including vegetarians and vegans. Though a vegetarian or

vegan diet can be perfectly healthy, vitamin B12 is naturally found only in animal products. As

such, it is important for these people to find a way to supplement their diet to prevent deficiency.

 The elderly. As people age, their bodies tend to become less efficient at processing nutrients. As

such, the elderly are more susceptible to nutritional deficiency and conditions such as atrophic

gastrisis, which can exacerbate a deficiency.


 People with intestinal disorders such as Crohn’s disease or celiac disease. These and similar

disorders inhibit the body’s ability to absorb nutrients from food, which means that even if these

people eat a well-balanced diet, they will not get all of the nutrients that they need. Regular takers

of acid-reducing drugs may consider vitamin B12 as it can reduce some of the negative effects

associated with taking these drugs.


 People with long-term illnesses such as diabetes, osteoporosis, muscular degeneration, and Lou

Gehrig’s disease tend to fare better when they supplement their diet with vitamin B12.


 Vitamin B12 is available in several forms such as pills, skin patches, and injections. Of these methods,

injections are more highly recommended as only injections provide absolute assurance that the vitamin will

be directly absorbed and used by the body. The benefits of B12 injections are higher than other

supplements because very little of the nutrients are wasted.
